Sažetak

This paper deals with the comparison of the seamless pulling process of precision seamless tubes using two different reductions from the viewpoint of geometrical stability using computerized tomography, from the point of view of mechanical properties, from the point of view of the surface temperature in the arrangement of the tribological tube-tool pair. Validation of the pipe drawing process also took place based on the finite element method in the simulation program DEFORM 3D. From the point of view of production rationalization, it is necessary to analyze stress and deformation states at different input dimensions for a particular final dimension for a given drawing method, in this case, a drawing whiteout plug method was used.
